Hello, lung cancer is a malignant tumor caused by abnormal, cancerous changes in lung tissue cells. This disease is not contagious. Common infectious diseases are typically caused by bacterial or viral infections and require three elements for transmission: a source of infection, a route of transmission, and a susceptible population. Therefore, you can safely engage in everyday contact with cancer patients. Moreover, cancer patients often experience low mood; thus, they usually benefit from emotional support and encouragement from family members. We hope this information is helpful to you. Wishing you a happy and fulfilling life!
